WRAPPING- SPECIFICATION forming part of Letters Patent No. 610,344, dated September 6, 1898.

Application filed December 31,1897. Serial No. 665,163. (No model.)

To all whom it may concern,.-

Be it known that I, LUTHER C. OROWELL, a citizen of the United States, residing at New York, (Brooklym) county of Kings, and State of New York, have invented certain'new and useful Improvements in Vrappin ig-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part4 of the same. y

This invention relates to machines of that class employed in Wrapping newspapers and other publications or similar articles, and esi pecially to machines whereby a lsuccession yof independent papers or other articles to vbe wrapped are advanced and enveloped in wrap# pers wound spirally about the successive pal pers as they are longitudinally advanced, the edges of successive vlayers or windings of wrapper overlapping and being secured by a line of paste applied by suitable pasting devices to one edge of the wrapper.

One of the objects ofthe' present invention is to provide a mechanism by which wrappertubes for enveloping successive papers as they are longitudinallyadvanced areformed from independent wrappers, and especially to form such independent wrappers into spirally; wound wrapper-tubes about the papers.- By thus forming the wrapper-tubes from independent wrappers I avoid the necessity of severing the wrappers between successive papers after wrapping, as is necessary when a continuous wrapper-web is formed into a continuous spirally wound wrapper tube about the papers, and I am thus enabled to inclose the papers in wrapper-tubes of considerablyless length than the papers. It will be understood, however, that the invention is not to be limited to forming the wrappertubes from independent wrappers, but that I may employ a continuous wrapper-web to form a continuous spirally-wound wrappertube about the papers, suitable means being provided for afterward severing the wrappertube at or near the junction between successive papers.

In a machine constructed to embody the inventionV in the preferred form the papers are advanced in succession longitudinally through a tubular former, and the wrappertubes are formed upon said tubular former and advanced longitudinally thereon, so that successive wrapper-tubes will be engaged by the successive papers as they are advanced from the end of the tubular former, and thus delivered from theforme'r with and inclosing thepapers'. The wrappers are advanced for wrapping preferably in the form of a continuous web, which in amachine constructed tocarry out that feature of the invention of forming the wrapper-tubes from independent wrappers is severed to form independent Wrappers before reaching the former, the Wrappers being advanced to the former at an angle and the web being cut to form the independentwrappers on lines extending diagon'ally of the web and at an angle to the former. The wrappers being thus advanced at an angle to the tubular former are wound spirally about the former and advanced 1ongitudinally thereon, preferably by means of a driven formingbelt which turns spirally about the'w'rapper-tube former, so that the wrappers, beingentered between the forniing-belt and the former, will be advanced spirally about the former by the belt to form spirally-wound wrapper-tubes.

The papers may be advanced to and through the tubular former by any suitable mechananism; but I preferably provide a receivingpocket having a longitudinal slot, through which the papers are successively folded into the pocket by a reciprocating folding-blade, and from which pocket they are advanced into the tubular former, preferably by means of pushers engaging the rear ends of the successive papers. As the papers after having been thus folded and fed through the former are advanced from the end ofthe former the tendency is for them to unfold or expand as they leave the former. Consequently a wrapper-tube advanced about the former and beyond the end thereof in time with the paper as it is advanced from within the former will be engaged by the paper as it expands after leaving the former and the paper `and the wrapper-tube will be delivered together, the paper inclosed by and fitting snugly within the Wrapper.

As a full understanding of the invention can best be given by a detailed description of a preferred construction embodying all the IOO features of the invention, such a description will now be given, in connection with the accompanying drawings, showing such a preferred construction, and the features forming the invention'will afterward be specifically point-ed out in the claims.

In said drawings, Figure 1 is a side elevation of a wrapping-machine embodying the invention, looking in the direction of arrow 1 of Fig.V 2. Fig. 2 is a plan view. Fig. 3 is a section on line 3 of Fig. 2. Fig. 4'is an end view looking in the direction of arrow 4 in Fig. 2. Fig. 5 is an elevation of the other end of the machine, looking in the direction of arrow 5 in Fig. 2; and Fig. 6 is a view looking in the direction of arrow 6 in Fig. 2, showing the opposite side of the mechanism for applying the wrapper from that shown in Fig. 5.

Referring to the drawings, the papers to be wrapped having been folded to the proper size are advanced in succession for wrapping between feeding-tapes 10 and 11, turning on rolls 12 and 13, the papers being advanced from the rolls l2 and 13 over a paper-receiving pocket 14, into which they are folded by means of a reciprocating folding-blade 15, carried by an arm 16 on a rock-shaft 17, and from which pocket they are advanced longitudinally of the pocket for wrapping. A supporting-guide 18 is preferably provided for the papers as they are advanced from the rolls 12 13, having a stop 19 for engaging the papers when they have been advanced in proper position over the pocket 14, and having an opening 20, extending parallel with the folding-blade 15, through which the papers are folded by said blade into the pocket. The folding-blade and pocket preferably extend transversely to the direction in which the papers are advanced bythe tapes 10 and 11, so that the papers as they are advanced from the rolls 12 13 will be folded into the pocket and then advanced transversely to the direction in which they are fed by the tapes 10 and 11.

The pocket 14 registers with a tubular wrapper-former 25, through which the papers after having been folded into the pocket are advanced to be inclosed 'in wrappers, as hereinafter described. This former 25 is preferably formed of a cylindrical tube 26, which is preferably extended to form the receivingpocket, the portion forming the receivingpocket having a longitudinal slot 27 for receiving the papers. The papers after being fold ed into the receiving-pocket are advanced longitudinally thereof and through the tubular former 25 by pushing-lugs 28, carried by a sprocket-chain 29,which lugs extend through a slot 30 in the part of the tube 26 forming the receiving-pocket to engage the rear ends of the successive papers in the pocket. The sprocket-chain 29 turns on sprocket-wheels 31 `and 32, between which thepushing-lugs 28 travel through the slot 30 and about a driving sprocket-wheel 33.

The pushing-lugs 28 are arranged at suitable distances apart and the sprocket-chain is driven at the proper speed for causing the lugs to engage the rear end of successive papers as they are folded into the pocket 14 and to advance them longitudinally of the pocket and into the former 25. Each paper after being advanced by the lug engaging its rear end beyond the path of the lugs rests in that position until engaged by the succeeding paper, by which it is then further advanced through the former 25 and finally delivered from the end of the former inclosed in its wrapper, as hereinafter described.

The wrappers are formed into wrappertubes about the tubular former 25 and advanced on the former and from the end thereof in time so that successive wrapper-tubes will meet successive papers as the latter are advanced from within the former. As the folded papers are advanced from the end of the former they tend to unfold or expand as they leave the former, so that when a paper and wrapper-tube are advanced from the former together the paper will expand, so as to engage and fit snugly within the wrapper-tube.

The wrappers are preferably formed about the former 25 substantially as follows: The wrappers are` advanced about the former to form wrapper-tubes by means of an endless wrapper-forming belt 40. The belt 40 runs from a driving-roll 41 to the former, about which it is turned spil-ally and from which it extends on the other side of the former to a second driving-roll 42, turning on said driving-roll, and running to a guiding-roll 43 above the roll 42, thence to a second guidingroll 44 above the roll 41, and thence back to thedriving-roll 41, theaxes of the guidingrolls 43 and 44 being set at an angle relatively to the axes of the rolls 41 and 42 to properly guide the belt in its movement from the roll 42 to the roll 41 and cause it to be maintained in proper position on said rolls to turn spirally about the formernin its run from the roll 4l to the roll 42. The wrappers are fed to the former and entered between the former and the forming-belt 40 to be advanced and wound about the former by the forming-belt to form a wrapper-tube, the forming-belt also acting, by reason of its spiral movement, to advance the wrapper and the formed wrapper-tube longitudinally on the former out of the path of the succeeding wrappers as they are advanced to the former to be wound thereabout by the forming-belt. The wrappers are preferably advanced in the form of a continuous web from a web-roll 45, carried by arms 46 on the frame,'the web passing between feeding-rolls 47 and 48, over a guide-roll 49, and between feeding-rolls 50 and 5l, by whichthe web is severed into independent wrappers. The wrappers are then turned up around the feeding-roll 51 by means of curved guides 52 and advanced over guides 53 beneath the forming-belt 40 to the former at an angle corresponding to the angle at Ioo which the forming-belt runs to the former, and entered successively between the former and the forming-belt, andV then advanced spirally about the former by the forming-belt to form spirallywound wrapper-tubes, the edges of the wrappers overlapping and being secured by a line of paste applied at one edge of the wrappers, as by means of a paste-roll 54, rotating in a fountain 55. For the purpose of severing the wrappenweb into independent wrapper lengths, the feeding-roll 50 is provided with a diagonal cutting-blade 56, coacting with a corresponding slot 57 in the roll 51 to sever the web as it passes between the rolls 50 and 51 on lines diagonal to the length of the web and at right angles to the former 25. The rolls 50 and 51 are of such diameter that at each rotation a length of the wrapper-web will be advanced sufficient to form a wrapper-tube of the desired length. The successive wrapper-tubes will thus be formed from successive independent wrappers, each of which will be wound spirally about the former to form a spirally-wound wrapper-tube and advanced thereon to make way for the next Wrapper. For the purpose of aiding in advancing the formed wrappert-ubes longitudinally on the former after they have been advanced beyond the forming-belt 40 I preferably provide a feeding-belt 60, running from a roll 61, beneath the former, and to a driving-roll 62, from which it returns over a ianged guide-roll 63 to the roll 61, the rolls G1 and 62 being positioned so that the belt vwill run in feeding contact with the wrapper-tubes as they are advanced from the feeding-belt 40,-so as to advance them spirally toward the end of the former after they have been advanced beyond the feeding-belt 40. With the wrapper-forming mechanism thus operating to form wrapper-tubes lsuccessively about the former and to advance them longitudinally thereon, and with the paper-feeding devices advancing the papers successively within the former, and in proper time with relation to the operation of the wrapper-forming devices, as each paper is advanced from the end of the former a wrapper-tube will be advanced to be engaged by the paper as the latter expands on leaving the former, and then by the further movement of the paper the wrapper-tube will be advanced with the paper, and the paper with the wrapper enveloping the saine will be delivered together from the end of the former.

The former is preferably made slightly smaller outside for a short distance from its end, as shown in Fig. 3, than at the part about which the wrapper-tubes are formed, so that the wrapper-tubes may be more readily drawn off from the former by the papers.

It will be seen that a machine may be constructed according to the invention to wrap papers in wrapper-tubes of any desired length relatively to the papers-as, for example, to wrap the papers in wrapper-tubes of a less length than the papers, as in the machine were desired to wrap the papers in wrapper-A tubes of greater length relatively to the papers, as of Ya length equal to that of the papers or greater than that of the papers, this could be accomplished, as will be readily understood, by causing the wrapper-forming devices to operate at a higher relative speed and to form longer wrapper-tubes, the rolls 50 and 51 being for this purpose made of a larger diameter; or, again, the machine shown might be employed for wrapping shorter papers; but for this purpose a sprocket-chain having the pushin g-lu gs 28 set closer together and driven at a correspondingly slower speed would preferably be used, so as to lessen the intervals between the successive movements of the papers as they are advanced in the former.

The various moving parts of the machine are driven from the driving-shaft as follows: The shaft 17 is rocked for reciprocating the folding-blade 15 by means of a cam 76, carried by a shaft 77, engaging a cam-roll on a pitman 78, pivoted to an arm 79, carried by the shaft 17, and having its other end forked to extend over and be guided by the camshaft 77. The shaft 17 also carries an arm 80, to which is connected a spring 81 for rocking the shaft to return the folding-blade after it has been moved on its forward movement by the cam 76. The cam-shaft 77 is driven from a gear 82 on the driving-shaft 75 through intermediates 83 and 84E, the intermediate 84 meshing with the gear 85 on the cam-shaft.` The driving sprocketwheel 33 is driven by a bevel-gear 86 on the cam-shaft 77, which gear meshes with a bevel-gear 87 on the shaft of the sprocket-wheel. The feedingrolls 47 and 48 carry intermeshing gears 90 and 91, respectively, and are driven from a gear 92 through an intermediate 93, meshing with the gear 90, the gear 92 being carried by a shaft which also carries a bevel-gear 94, which is driven by a bevel-gear 95 on the driving-shaft 75. The shaft of the belt-feeding roll 4.2 carries a gear 96 and is driven from the gear` 90 through intermediates 97 and 98, the latter of which meshes with the gear 96. The feeding and cutting rolls 50 and 51 carry intermeshing gears 100 and 101 and are driven by the gear 92, which meshes with the gear 100. The belt-feeding roll 41 carries a gear 102, which meshes with and is driven by the gear 101. The driving-roll 02 for the `auxiliary feeding-belt 60 is driven by a gear 103, car- IOO IIO

ried by the shaft of the feeding-roll 4:7 ,through gear 104, bevel-gears 105 and 106, and gear 107, the latter meshing With a gear 108 on the shaft of the driving-roll 62. The'shaft of the pasting-disk carries a gear 110, meshing with the gear'lOl of the feeding-roll 51.
